Football Game Project

This game was originally written for my major assignment in Real-Time Rendering and 3D Games Programming subject. However, it has been changed to accommodate more features; such as being able to choose the formation of each team.

The game was inspired in a popular game in Brazil called Button Football.

The game was written in C using OpenGL, SDL and ODE.

Game Objectives

This is a 2 player game where the player who scores three goals first wins.
Each player has two turns to shoot, being able to control the ball orientation and the force.

Usage

Pre-requisites

Before compiling you must have the libraries for OpenGL, SDL and ODE.

Compiling and Running

1. Compile using the Makefile provided by typing “make”. It should produce an executable called “football”
2. Run “football” by typing ./football

Commands

Key	Action
Escape	Menu
F	Displays frame rate
Arrows	Ball orientation
Spacebar	Force
Left mouse button + mouse movement	Moves camera
Mouse movement	Tilt camera

Functionalities

Gameplay

Ball orientation: Player can see where to shoot using the small ball that moves with the force and orientation. The small ball changes colour according to player’s turn; blue for player 1 and green for player 2.

Ball contact: The ball bounces off walls and objects when it hits them.

Out of Bounds: When the ball goes out of bounds it is brought back to the position where it was shot.

Goals: A goal is counted only when the whole ball enters the goal.

Physics

ODE: The ODE Physics Engine was used for all the physics in the game. The engine is responsible for all the friction and collision detection in the game.

User Interface

Formation: Each player can choose the formation before each game.

Camera: User can walk and tilt camera to change view.

Other features

Load formation: The team formation is loaded from file; thus it is configurable.

Texturing: The walls and the sky have textures; coordinates are generated automatically because it is a sphere.

The scoreboard and menus are switched to ortho2d mode before creation. So they won’t rotate with the rest of the objects.

Ball movement: The ball is moved in real time from position retrieved from the ODE Engine.

Lights and smooth shading: All objects that are not textured have lighting and smooth shading.
